Combine all the sauce ingredients in a bowl (everything except beef and broccoli) and whisk together.
Put beef into a gallon size bag and pour the sauce into the bag, too. Marinate for up to 1 hour before cooking.
Pre-heat a cast iron pan (or large fry pan) to medium-high heat. Chop broccoli heads to bite-size florets.
Add 1 tablespoon avocado oil to the pan and then pour the meat and marinade into the pan. Cook For about 8 minutes or until beef is almost cooked through.
Add broccoli to the same pan and cover. Cook for 5 minutes or until broccoli is fork tender.
Serve over your favorite rice and top with green onions and sesame seeds. Enjoy!
Notes
Marinade the meat for about an hour before cooking. If you don't have time for this then combine all the ingredients into a bowl for pouring over the meat.
Use Greensbury pre-cut Organic Grass-fed Beef Fajita for a quick and easy meal. If not you can use a flank steak.
Serve this over your favorite rice! Cauliflower rice is great if you are doing a Whole30 or you can use any other rice that you like best.
This saves great for left-over lunch the next day or could even be frozen for a meal later in the month.
